Research Associate Professor, Mechanical Engineering
Dr. Zhu has been developing the theory, modeling, and computational software for a wide array of chemically-reacting fluid-flow problems including: combustion, catalytic processes, chemically-reacting reservoir flows, high-temperature MIEC membrane reactors, solid oxide fuel cell systems, and batteries. Recent efforts include new approaches and software to represent the coupled effects of electrochemical kinetics, thermal reforming kinetics, porous-media transport, and fluid flows.
These capabilities are also incorporated into system-level models, which are applied to evaluate and optimize solid-oxide fuel-cell systems and batteries. Dr. Zhu is also studying the heterogeneous chemical reaction mechanisms for the fuel processes, catalytic combustion, and electrochemical systems for clean-energy power-conversion technologies.
